Description

[Technical Field]

[0001] The present invention relates to a vehicle for use in a work area, the vehicle comprising a screen, the screen comprising a screen element and a fixing element, the screen being fixed to a transport position outside the vehicle by the fixing element. Furthermore, the present invention generally relates to a screen that can be fixed to a vehicle, and to a method of shielding a work area, and corresponding uses of the vehicle or screen. [Background technology]

[0002] When an accident occurs on a busy road, drivers of vehicles passing through a work zone are often tempted to slow down so they can see the people in distress and the work zone. This can slow down traffic flow, which can lead to congestion. Distraction of passing drivers can lead to rear-end collisions. As a result, police officers, paramedics, or firefighters working in the work zone are not only hindered in their work, but also put at great risk to their safety.

[0003] In order to avoid impairing traffic flow and the associated inconveniences, many devices are known from the prior art for shielding work areas from the view of passing drivers.

[0004] For example, U.S. Patent No. 4,186,912 discloses a folding screen comprising a strip of fabric and a pole with a fixed cable. The fabric is made of a light-reflective material to warn pedestrians and has strips to prevent wind damage. However, assembling this screen takes time and requires a large amount of space in the emergency vehicle to transport it.

[0005] U.S. Patent No. 6,036,249 relates to a screen for screening a work area, which, in its installed state, is fixed to the exterior of a vehicle and comprises a plurality of panels. The panels may include a foldable frame portion. Thus, the panels can be folded, allowing the screen to be stored in the trunk. Again, assembling and disassembling the screen is time-consuming, and the screen occupies a large amount of space within the vehicle.

[0006] EP 2 460 938 A1 discloses an inflatable shielding plate. However, fixing it is difficult, especially in windy conditions. It also has the disadvantages of tedious assembly and disassembly, and the need for time-consuming drying when the inflatable shielding plate gets wet during use.

[0007] U.S. Patent Application Publication No. 2020 / 0378077 describes a rollable screen for shielding a work area that is wound around a wrapping device within a towable trailer, and in a deployed state, the screen can be spread between the trailer and an emergency vehicle.

[0008] French Patent Application No. 2,686,914 also describes a roll-up screen for screening a work area. The screen is wound on a roll fixed to the exterior of the emergency vehicle. For protection, the screen can be provided with a cover, which can be removed as needed, allowing the curtain to unfold. The edges of the curtain can be fixed to fixed objects, such as trees or other emergency vehicles. This screen has the disadvantage that it cannot guarantee a distance to the work area. Rather, the flexibility of the curtain allows the screen to be adapted to the work area, but in that case, the curtain is attached directly to the vehicle involved, which makes working in the work area more difficult. Summary of the Invention [Problem to be solved by the invention]

[0009] The object of the invention is to provide a shield for a vehicle of the type mentioned at the outset, which can be adapted to the working area while maintaining a distance. [Means for solving the problem]

[0010] This object is achieved according to the invention in the vehicle of the type mentioned at the outset in that the shielding plate has a frame, the shielding plate elements are connected to the frame and the frame is connected to a fixing element.

[0011] The present invention further generally relates to a shielding plate for shielding a work area, the shielding plate comprising a shielding plate element and a fixing element, the fixing element configured to fix the shielding plate to a transport position outside a vehicle, the shielding plate comprising a frame, the shielding plate element connected to the frame, and the frame connected to the fixing element.

[0012] The dimensional stability of the frame allows the screen to be adjusted without support from related objects in the work area (e.g., vehicles, trees), maintaining the distance between the screen and the work area. The frame can be rectangular, resulting in good screenage of the work area. In this case, the frame can have two rods on each side or four rods on all four sides. For weight reasons, the poles can be made of a light metal such as aluminum, so that the screen can be easily installed by one or two people. The frame can also be designed as a plate or panel, in particular as a metal panel.

[0013] When the shielding plate is fixed to a minibus, the frame may be 130-170 cm wide and 150-190 cm high. When the shielding plate is fixed to a larger vehicle, in particular a fire engine, the frame may be up to 200 cm or 250 cm wide and up to 300 cm or 350 cm high. Furthermore, the frame may be designed so that it does not rest on a base when the shielding plate is in the installed state. For example, the distance from the base to the frame may be in the range of 10-50 cm. However, it is also possible to design the frame so that one side of the frame rests on the base when the shielding plate is in the installed state.

[0014] The frame can be articulated to at least one other frame. This allows for shielding a larger surface area of ​​the work area or shielding the work area from several sides. Screen lengths of up to 10 or 15 meters, and even up to 25 meters for fire engines, can be realized. The connection can be made, for example, by a ball-and-socket joint or a hinge joint. In this case, two adjacent frames can each have a joint. Two or more, especially two, joints can be provided between two frames to ensure good stability and load-bearing capacity. Furthermore, the articulated connection simplifies folding of the frames, allowing the screens to be easily and space-savingly fixed to the exterior of the vehicle and quickly installed by unfolding the frames as needed.

[0015] To prevent the frames from accidentally pivoting relative to one another when the shield plate is in the installed state or transport position, the joints can be designed to be correspondingly stiff. A drop bar latch can be fixed to one side of the frame adjacent to the side intended for connection to another frame. The drop bar latch can be screwed to the frame, for example. In the installed state of the shield plate, the drop bar latch can be rotated 180° to form a positive connection of the frame to which it is fixed to the adjacent frame. However, for geometric reasons, this is only possible if the frames are not pivoted relative to one another and are arranged along a straight line. To increase the positive connection force between two adjacent frames formed by the drop bar latch, the drop bar latch can be provided with a protrusion for receiving in a corresponding recess on one side of the frame. For example, the protrusion can be rectangular parallelepiped-shaped so as to be received in a corresponding rectangular parallelepiped-shaped recess in the frame. To prevent the frames from accidentally pivoting relative to one another when the shielding plate is in the transport position, tensioning elements may be provided which press the frames together. The tensioning elements may comprise, for example, tensioning clamps or tensioning straps. Also, multiple tensioning elements, for example two or three tensioning elements, may be provided at intervals.

[0016] If the screen has two or more frames, these can be connected to one another by a double joint, which allows the frames to pivot on both sides of one another (swing door principle). By appropriately pivoting the frames relative to one another, the screen can be particularly well adapted to the working area. The double joint can be designed, for example, as a double hinge joint or a double ball joint.

[0017] If the shielding plate has two or more frames, support wheels may be fixed to at least one of these frames. This allows the shielding plate to be easily rolled to the desired position. For particularly long shielding plates, support wheels may be provided at regular intervals to reduce the force acting on the connections (e.g., joints) between the frames. Although the shielding plate, which can weigh up to 160 kg (depending on the number of frames and the material of the shielding plate), can be carried by one or two people, rolling it is much easier and less physically demanding. The support wheels may be closable to ensure a stable grip when it reaches the desired position. In strong winds, the support wheels can also be weighted, for example, with sandbags. If support wheels are provided, the frame should be designed so that the frame does not come into contact with the base, since a contact surface between the frame and the base would prevent the shielding plate from rolling due to friction. The support wheels, especially if designed to be closable, provide additional stability to the shielding plate in the installed state. The support wheels may be fixed to one of the frames via rods. The fixing can be performed, for example, by a screw connection. The rod can be extendable (for example, an extendable arm) to flexibly adjust the distance between the frame and the base. For example, a support wheel can be provided for every two frames.

[0018] The fixing elements may be connected to the frame by positive and / or non-positive connections. Articulated connections, for example by ball-and-socket or hinged joints, are also possible to allow maximum freedom of movement when installing the screen. The fixing elements may have suction cups to secure them to the exterior of the vehicle, for example to a smooth exterior surface, in particular a window pane. The fixing elements may have cables or hooks to suspend or wrap them around a suitable location on the exterior of the vehicle (for example a bracket, roof rail or roof rack). Alternatively, the fixing elements may have snaps, bolts, pins, screws, plugs, clamps, clips, hook-and-loop fasteners or part of an articulated connection for fastening to the vehicle, with the other part of the respective connection being located on the exterior of the vehicle.

[0019] The fixing element can be connected to the frame via a spacer, which avoids interfering with the opening of the vehicle door. For example, when the shielding plate is fixed to the side of the vehicle, it is possible to open the sliding side door that is often provided on emergency vehicles. The spacer can also be used to fix the shielding plate near the exterior mirror of the vehicle, bridging this distance relatively far from the vehicle without damaging the exterior mirror. The spacer can be designed to be extendable, for example by means of an extendable arm (e.g., a telescopic arm), in order to adjust the distance to the vehicle as desired. For example, the spacer arm can be made of stainless steel (NiRoSta) for good weather resistance.

[0020] The spacer and the frame can be connected to each other by a rigid connection (e.g., screws, rivets, adhesive, solder, articulated connection, or welded connection) or a movable connection. In particular, the spacer and the frame can be connected to each other in an articulated manner, which allows the shielding plate to be installed at any angle relative to the vehicle. An articulated connection also allows the spacer and the frame to pivot relative to each other so that the shielding plate can be stored compactly. The spacer and the frame can be connected to each other by, for example, a hinge joint or a ball-and-socket joint. To prevent the spacer and the frame from accidentally pivoting relative to each other while the shielding plate is being transported or in an installed state, the joint can be designed to be correspondingly stiff. The spacer can have struts, such as diagonal struts, which can increase the rigidity of the connection between the spacer and the frame and therefore the stability of the shielding plate. When the spacer is articulatedly connected to the frame, the struts may be articulatedly connected to the spacer or the frame so as not to impede mobility.

[0021] The shielding element connected to the frame serves, on the one hand, to shield the work area from the prying eyes of passing motorists. On the other hand, in the event of sideways rain or wind, the shielding element may also serve to protect personnel in the work area. Furthermore, the shielding element may function as an advertising banner. The shielding element may be made of metal, fabric, plastic, or a combination thereof. As the risk of fire in traffic accidents may be high, fire-resistant shielding elements may be used. For example, the shielding element may be made of one or more metals, or of fabric and / or plastic, in particular fire-retardant plastic, optionally with a metal coating.

[0022] If a substantially rigid, e.g., metallic, shielding plate element is used, the shielding plate can be connected to the frame, e.g., by welding, in this way the frame can be partially and fully embedded. Due to the good heat resistance of metallic shielding plate elements, it can be advantageous to use them in fire brigade operations or generally in cases of fire danger.

[0023] Depending on the rigidity of the shielding plate element, it may be sufficient to design the frame as two opposing rods, or, if the shielding plate element provides sufficient stability, to form the frame and the shielding plate element from the same substantially rigid panel or pane, for example made of metal or plastic. In embodiments that are as light as possible in terms of weight, the shielding plate element may comprise a light metal, in particular aluminium.

[0024] If the shielding plate has several frames, all frames can be connected to the same type of shielding plate element. However, a combination of different shielding plate materials in different frames is also conceivable. For example, one frame can be connected to a metal shielding plate element, while another frame can be connected to a plastic and / or fabric shielding plate element. This makes it possible to achieve a good balance between the stability and weight of the shielding plate.

[0025] When a screen element comprising fabric and / or plastic is used, the screen element can be secured to the frame by bands, for example, via eyelets, slots, or tunnels built into its edges. In particular, the screen element can be made of net vinyl, a PVC-coated mesh fabric that is weather-resistant, UV-resistant, tear-resistant, flame-retardant, and dimensionally stable, making it well-suited for outdoor use. Due to its good printability and high color brightness, mesh vinyl is also well-suited for advertising banners.

[0026] The shielding plate element may have holes, thereby reducing resistance to lateral forces such as wind loads. The holes may have a diameter or side length in the range of 0.5 to 4 mm, in particular 1 to 2 mm. Overall, the holes may occupy up to 20%, or even up to 30%, of the area of ​​the shielding plate element. As a result, a significant reduction in resistance to shear forces may be realized, while at the same time providing good privacy.

[0027] The shielding plate elements may be elastically connected to the frame. The elastic connection may reduce the risk of damage to the shielding plate elements due to lateral forces, such as wind loads, since lateral forces may be captured in the elastic, and therefore stretchable, connection. The elastic connection may be realised, for example, via an elastomer band or a spring.

[0028] For example, the shielding plate element may be connected to the frame in its corner regions, in each case via elastomer bands or springs, which may also be arranged evenly distributed over the periphery of the shielding plate element for connection to the frame.

[0029] Also, when using elastomer bands, one elastomer band may be stretched adjacent to each of two opposing sides of the frame, parallel to these sides, and the shielding plate elements may then be fixed to the elastomer bands, for example, via eyelets, slots or through tunnels through which the elastomer bands can pass, integrated into the edges of the shielding plate elements.

[0030] The shielding plate element may be movable relative to the frame. This may be possible, in particular, if the shielding plate element is fixed to the frame via an elastomer band, allowing the shielding plate element to move along the elastomer band. Alternatively, the shielding plate element may be attached, for example, to a rail guide within the frame. By moving the shielding plate element to one side of the frame (like a curtain), an opening is designed in the frame, allowing emergency responders to pass through. In this way, they can quickly pass from one side of the shielding plate to the other, whereas otherwise they would have to bypass the shielding plate and possibly the vehicle, which would take a considerable amount of time and would be inconvenient, especially in an accident situation. Furthermore, the surface perpendicular to lateral forces (e.g., wind loads) can be reduced, which may facilitate the installation of the shielding plate, for example, in wind.

[0031] Alternatively, the shielding element may have two slats that can be moved relative to one another. For this purpose, for example, two bands, particularly elastomer strips, can be fixed to the frame parallel to and adjacent to two opposing sides of the frame. In this case, the two opposing bands function as a band pair. Each pair of belts can be used to receive a slat so that the slats can be positioned in the frame offset relative to one another. Then, in the transport position and when installing the shielding element, the slats can be moved to one side of the frame and positioned one above the other. The slats can be fixed to the bands via eyelets or slits. Alternatively, tunnels through which the bands can pass can be integrated into the edges of the slats. For example, two to six slats, particularly three slats, that can be moved relative to one another can be provided in the frame, which allows for a significant reduction in wind loads when installing the shielding element. As in the case of vertical blinds, the slats may also be rotatable, so that they can be rotated, for example, by 90°, to reduce wind loads. As an alternative to bands, it is also possible to provide parallel guides, such as parallel guide rails for the slats in the frame, on one side or on two opposite sides. The slats may be arranged in a common guide rail so that they can move relative to and out of alignment with each other.

[0032] The screen may further have at least one support leg connected to the frame or to at least one of the frames. One end of the support leg may have a narrowing or tapering to obtain better grip on soft surfaces (e.g., gravel, grass). One end of the support leg may be provided with a flat support surface to obtain a better footing for the screen on hard surfaces (e.g., asphalt). Spikes may also be arranged on the support surface. The support surface may be foldable, for example using a hinge joint, so that the screen can be folded for transport and can rest against the support leg, or in the case of multiple frames, so that the folding of the frames is not hindered by the support surface.

[0033] The support legs can be connected to the frame via connecting elements, which can be, for example, joints, in particular hinge joints, so that in the transport position of the shielding plate the support legs can be folded up so that they can rest against the frame, thereby allowing compact storage of the shielding plate.

[0034] The support legs may be movable relative to the frame so that they can rest against the frame in the transport position of the shielding plate. For this purpose, sleeves or clamps may be provided on one side of the frame, which can be pressed onto the support legs for fixing purposes. If desired, the sleeves or clamps can be fixed in a specific position using, for example, nails, screws or hook-and-loop fasteners. For example, the support legs can be held in the transport position by screws provided on one side of the frame with corresponding geometric shapes, such as acute-angled recesses at both ends of the support legs. By providing several screws, a better grip can be ensured, or the support legs can also be held in various positions by screws, for example in the transport position of the shielding plate and in the installed state.

[0035] For better stability, struts may be provided between the frame and the support legs, and the struts may be articulatedly connected to the support legs. In strong winds, the support legs may be secured with weights, such as sandbags. For example, sandbags may be placed on the support surfaces of the support legs. An anemometer or wind meter can be used to determine the wind strength at which the use of weights is advantageous.

[0036] Also, for particularly good stability, two opposing support legs may be fixed to the frame, in which case, in the installed state of the shielding plate, a V-shaped support may be provided by the two support legs.

[0037] If the shielding plate has two or more frames, the support legs can be fixed, preferably at regular intervals, for example one every two frames. As a result, a better grip is achieved so that the shielding plate can particularly well withstand lateral forces, in particular wind loads. The support legs can be arranged offset so that two adjacent support legs are each arranged on different sides of the frame, thereby providing support on both sides. To obtain particularly good support, two mutually opposing support legs can also be arranged every two frames. In the installed state of the shielding plate, the support legs can then provide a V-shaped support.

[0038] The screen may also have a camera fixed to or integrated into the frame, allowing the work area to be recorded for documentation purposes. If the camera is fixed to the frame, the fixation may be achieved, for example, by a clamp, clip, or screw connection. If the camera is integrated into the frame, the camera may be flush with the frame to ensure good protection. The camera may be battery-powered or rechargeable, but may also be connected to the vehicle's circuitry. The camera may have a camera arm so that it can digitally capture the work area from above. Several cameras may also be mounted on the frame to capture the work area from several angles. This is particularly useful for screens with multiple frames, in which case, for example, one camera may be mounted every two or three frames. Alternatively, one camera may be mounted on each of the two sides of the frame, facing opposite directions to ensure that the work area is documented by the camera facing the work area, regardless of the positioning of the screen relative to the work area.

[0039] The shielding plate may also have a light source fixed to or integrated into the frame. This allows for illuminating the work area and facilitating emergency services, especially at night. If the light source is fixed to the frame, the fixation may be performed, for example, by clamps, clips, or screw connections. If the light source is integrated into the frame, it may be flush with the frame to ensure proper protection. The light source may be an LED lamp or an incandescent lamp. Furthermore, the light source may be battery-powered or rechargeable. Connection to the vehicle's circuitry is also possible, and a power cable may be integrated into the frame and, if necessary, into the spacer. Light sources may be provided on the front and rear sides of the frame so that the light sources are directed in opposite directions and the work area is always illuminated regardless of the positioning of the shielding plate. In this case, only the light source facing the work area can be switched on. However, it is also possible to switch on the light source facing away from the work area to prevent passing drivers from inspecting the work area more closely. Of course, excessive glare must be avoided, preventing the driver's vision from being impaired. To ensure that the entire working area is well illuminated, the screen may also have several light sources on one side of the frame, which may for example be located at all corners of the frame or evenly distributed around it.

[0040] The fixing element of the screen may have a suction cup so that it can be fixed to the exterior of the vehicle, for example to a window pane. The fixing element may also have a cable that can be wound around and tied to, for example, a roof rack or roof rail of the vehicle. A clamp, in particular a clamp lock, or a carabiner may be provided at one end of the fixing element, for example at the cable end, to receive the end of the cable wound around the roof rack or roof rail and to enable a stable connection. Alternatively, a fixed connection can be achieved by tying. The fixing element may also have a hook, or a snap, bolt, pin, screw, plug, clamp, clip, hook-and-loop fastener, or part of an articulated connection, with the other part of the respective connection being provided on the exterior of the vehicle.

[0041] The fixing element may also have a gripper, for example, a three-finger gripper. The three-finger gripper may be articulated and fixed to the fixing element, particularly using a swivel joint. Each finger of the three-finger gripper may be provided with a hook or a ring to secure it in a suitable position outside the vehicle. If the gripper has a ring, the ring may be opened or attached, for example, by a clamp or screw. The gripper may comprise an elastic material, particularly an elastomer, so that the individual fingers of the gripper can be stretched relative to each other. Alternatively, the fingers of the gripper may be extensible, for example, like a telescopic arm, to change their length. For example, in a three-finger gripper, the two outer fingers may be extensible, while the middle finger may have a fixed length, thereby predefining a certain minimum distance between the frame and the vehicle. The extendable fingers may be provided with a damping element, so that sudden changes in the length of the fingers and associated damage to the vehicle or the shielding plate can be avoided.

[0042] The screen can be fixed at the transport position on the rear side of the vehicle. As a result, the screen can ensure that the vehicle is loaded evenly across its width, and tilting due to uneven lateral loading can be avoided. Furthermore, by fixing the screen to the rear side of the vehicle, a reduction in the visibility of the vehicle driver can be avoided as much as possible. Furthermore, an increase in the width of the vehicle can be avoided, which makes it easier to comply with regulations regarding the maximum width of the vehicle for participation in road traffic.

[0043] The shielding plate can be articulated to the vehicle, which allows for greater flexibility when installing the shielding plate. It is also possible to compensate for unevenness or inclination of the lower surface and the associated height difference between the vehicle and the installed shielding plate. For example, a hinge joint or a ball joint can be used. The joint can be designed to be correspondingly stiff to prevent the shielding plate from accidentally pivoting relative to the vehicle in the installed state or in the transport position.

[0044] The shielding plate may be fixed to a guide rail connected to the vehicle. That is, the vehicle may have a guide rail, the guide rail being fixed to the exterior of the vehicle, and the shielding plate being fixed to the guide rail. As a result, the shielding plate can be moved relative to the vehicle and installed starting from any position along the guide rail. The guide rail may be attached to the exterior of the vehicle by a suitable connection, in particular a positive and / or non-positive connection. For example, a screw connection has proven advantageous. To ensure dimensional stability while maintaining a relatively low weight, the guide rail may comprise high-strength aluminum.

[0045] The shielding plate can be fixed in a desired position along the guide rails, for example by using clamps, screws, clips or pins to secure the shielding plate in this position, thereby preventing undesired movement of the shielding plate.

[0046] The guide rail can be positioned directly adjacent to the vehicle, but it can also be spaced apart from the vehicle, for example at a distance of 1-20 cm. If the guide rail is spaced apart from the vehicle, a fixing element with a cable can be wound around the guide rail or a fixing element with a carabiner or hook can be suspended from the guide rail to secure the shielding plate.

[0047] The guide rail may be designed as an open profile and have a recess that is constant over its length, e.g., opening toward the side facing away from the vehicle or toward the side that is arranged perpendicular to the vehicle. The recess may therefore be approximately U-shaped. The cross section of the recess may, for example, taper in a wedge-like manner from the inside toward the opening. The fixing element may then be designed such that it can be pressed into the recess at one end of the guide rail. The fixing element should then be designed as a dimensionally stable object and have a cross-sectional area that substantially corresponds to the cross-sectional area of ​​the recess.

[0048] The fixing element may also be designed as a fixing clip, which can be inserted into the guide rail by compressing it and can adapt to the shape of the guide rail after release to achieve a positive connection. To provide sufficient stability, the fixing clip may be made of metal. For this purpose, for example, a guide rail with an open profile with an approximately U-shaped recess or a T-shaped profile may be used, as described above.

[0049] The shielding plate may be fixed to a carriage that is movable relative to the guide rail. This allows the shielding plate to be easily moved along the guide rail relative to the vehicle. Depending on the design of the fixing element of the shielding plate, the carriage may have a ring, a carabiner, a hook, or a snap, bolt, pin, screw, plug, clamp, clip, hook-and-loop fastener, or part of an articulated connection to the shielding plate. For example, the carriage may have a ring to which the carabiner, hook, or cable of the fixing element can be fixed. In particular, the fixing element and the carriage may each have part of a joint. For example, the fixing element may be designed as an articulated head, and a joint socket for receiving this articulated head may be provided on the carriage. A ball-and-socket joint may be provided to allow the shielding plate to pivot in all directions relative to the vehicle. In this way, not only can height differences due to ascending or descending surfaces be compensated for, but the shielding plate can also be installed at any angle relative to the vehicle. The carriage may be fixed to the guide rail by means of, for example, a screw, plug, clip or clamp connection. The carriage may also have a recess, starting from the free end of the guide rail, capable of receiving the guide rail.

[0050] The guide rails may also be positioned at least at the rear side of the vehicle and / or immediately adjacent to the rear side along the outside of the vehicle roof, making it easier to transport the screen along the rails to a transport position at the rear side of the vehicle.

[0051] The guide rail may also be arranged along the outer side of the vehicle's roof, adjacent to the longitudinal side and rear side of the vehicle, and the guide rail may be curved in the corner region of the roof. The longitudinal side is understood to mean one of the two sides adjacent to the rear side of the vehicle, where the vehicle's side door is located. Thus, the guide rail may be designed along a substantially L-shaped profile. When the guide rail is arranged along the outer side of the vehicle's roof, adjacent to both the longitudinal side and rear side of the vehicle, the guide rail may be designed along a U-shaped profile. The curved design of the corner region allows the shielding plate to easily move along the entire length of the guide rail relative to the vehicle. The radius of the curve of the guide rail may be within a range of 5 to 50 cm. This L- or U-shaped design of the guide rail allows the shielding plate to be installed starting from two or three sides of the vehicle. This allows for great flexibility, as the shielding plate can be installed regardless of the relative positioning of the vehicle to the work area. Therefore, the orientation of the vehicle does not need to be taken into consideration when installing the shielding plate as the vehicle approaches the work area. This is particularly advantageous in tight situations where it is difficult to turn or change the position of the vehicle in the work area.

[0052] If the fixing element comprises a gripper, in particular a three-finger gripper, each finger of the gripper can be fixed to a separate carriage. For fixing, a swivel joint can be provided for each. In the case of a three-finger gripper, the two outer fingers can be designed to be extendable, for example like telescopic arms. As a result, the difference in finger length can be adjusted in the curved portion of the guide rail, thereby allowing the shielding plate to move along the curved portion of the guide rail.

[0053] The shielding plate may also have two fixing elements connected to the frame, thereby fixing the shielding plate to the exterior of the vehicle. Each of the two fixing elements may be connected to the frame at a corner region on the same side of the frame. By fixing the shielding plate with the two fixing elements, pivoting of the installed shielding plate relative to the vehicle may be limited.

[0054] Each of the fixing elements may be connected to the frame via a respective spacer. Alternatively, both fixing elements may be connected to the frame via a common spacer. In this case, this spacer may have a first rod arranged parallel to one side of the frame at a distance. The first rod may be connected to the frame by joints. For example, two to six joints, in particular two joints, may be arranged equidistant from each other over the height of the side of the frame. The first rod may be connected at its two ends or in the end region to further rods, in each case by screwing or welding, for example, and these two further rods may be perpendicular to the first rod. A fixing element may be arranged at each end of the two further rods.

[0055] For example, two guide rails may be connected to the vehicle, with a first guide rail located in the floor area of ​​the vehicle and a second guide rail located in the roof area of ​​the vehicle. The first guide rail may be located outside the wheels of the vehicle so that the shielding plate can move freely along the guide rail. The first guide rail may also be designed in multiple pieces, and the portions of the first guide rail located near the wheels may be removed. In this way, when these portions are removed, the presence of the first guide rail does not interfere with wheel replacement.

[0056] By fixing the shielding plate to the transport position outside the vehicle, if the shielding plate gets wet at the work site, it can dry quickly (e.g., by a relative breeze). Furthermore, fixing the shielding plate to the transport position outside the vehicle has the advantage that no space needs to be provided inside the vehicle for the shielding plate.

[0057] In addition to fixing the shielding plate by the fixing elements, the shielding plate may also be fixed, for example, using hooks provided on the frame and corresponding pins located on the exterior of the vehicle, or a protrusion may be provided on the exterior of the vehicle onto which the shielding plate rests.

[0058] A cover may be provided to protect the screen during storage. The embodiment of the cover may depend on how the screen is fixed to the vehicle. If the fixation is a stable fixation that can absorb the additional weight of the cover, the cover may be designed, for example, as a rain-resistant plastic tarpaulin. If the fixation of the screen by the fixing elements is not sufficient to hold the screen well during transport, the cover may be made from a material with a relatively high rigidity, for example from metal and / or from fiber-reinforced plastic.

[0059] In addition to the fixing by the fixing elements, fixing means such as pins, hooks, clips or clamps may be provided in the cover to secure the shielding plate against slippage during transportation, and cable straps or hook-and-loop fasteners may be provided to better secure the shielding plate in the cover.

[0060] The cover may be designed as a box, which may be fixed to the rear side of the vehicle, for example by means of screws, and may have one or two pivot, sliding, folding or rolling doors to facilitate quick installation of the screen.

[0061] The cover may be provided with ventilation openings, e.g. ventilation slots, which allow air to be exchanged with the surroundings, thereby enabling the shielding plate to dry quickly even when it is stored in the cover.

[0062] The cover may have corresponding recesses for the fixing elements or the spacers (if present), so that the cover does not interfere with the fixing of the shielding plate to the vehicle.

[0063] The screen may also have a weather guard secured to the frame. The weather guard not only protects the screen from rain in the transport position, but also protects people in the work area when the screen is installed. The weather guard may be secured to the side of the frame facing away from the base. The weather guard may have a panel or plate that may be positioned at an angle of approximately 90° to the frame (thus allowing the weather guard to be positioned substantially parallel to the base). The weather guard may be secured to the frame by, for example, screws or nails.

[0064] The weather screen may also be pivotable so that it can be pivoted approximately 180°, i.e., from one side of the frame to the other. Therefore, regardless of which side of the frame faces the work area, the weather screen can be used to protect people in the affected area from rain. For this purpose, the weather screen may be fixed to the frame by a hinge joint. For example, two hinge joints may be provided for fixation. The hinge joints may be designed to be stiff so that the weather screen is held stable and accidental pivoting is prevented.

[0065] The present invention further provides a method for producing a pharmaceutical composition comprising the steps of: (a) driving a vehicle according to the present invention to a work area with the shielding plate in the transport position; (b) installing the shielding plate; The present invention relates to a method for shielding a work area, including:

[0066] To install the shielding plate, the attachment of the shielding plate to the vehicle provided in step (a) may be released, and the shielding plate may be fixed to another suitable position outside the vehicle by the fixing element. Alternatively, the fixation provided in step (a) may be maintained. Also, if a guide rail is provided to fix the shielding plate, the shielding plate may be moved along the guide rail relative to the vehicle.

[0067] In that case, the frame can be pivoted relative to the vehicle in order to align the shielding plate according to the working area, and if the fixing element is connected to the frame via a spacer, the spacer and the frame can also be pivoted relative to each other in order to align the shielding plate according to the working area.

[0068] In the transport position of the screen, the screen element may be moved to one side of the frame, or if the screen element has slats that can be moved relative to each other, they may be arranged one above the other, in which case after step (b) the screen element may be extended (like a curtain) or the slats may be moved relative to each other and arranged next to each other to ensure that the work area is screened.

[0069] If the frame is provided with support wheels and the support wheels are fixed to the frame via telescopic rods, the rods can be extended and fixed, for example, locked and clamped, so that the shielding plate can be rolled to a desired position or the distance between the base and the frame can be adjusted.

[0070] If the frame has support legs, the support legs may be moved after step (c) into a position suitable for supporting the frame, for example by unfolding the support legs and / or by moving them in particular vertically relative to the frame.

[0071] The frames of the screen may be articulated to at least one other frame, and in the transport position, these frames may be folded. Then, during installation, these frames can be at least partially unfolded. This allows for the screen to cover a larger working area, resulting in screen lengths of up to 10 m, or even up to 25 m, depending on the number and width of the frames (which depends, among other things, on the type of emergency vehicle). As a result of at least partial unfolding, any desired angle of the frames relative to one another can be achieved.

[0072] During installation in step (b), the shielding plates can be positioned in an appropriate manner in the work area. They do not depend on special conditions of the work area, such as trees or utility poles. Rather, the shielding plates can be freely positioned, for example, within the street plane. For example, the position of the installed shielding plates can be selected depending on the line of sight of passing vehicle drivers so as to achieve sufficient shielding without enclosing the entire work area. Furthermore, the shielding plates can be installed to ensure unhindered access to the work area and to people and objects involved in the accident, particularly from all sides. For example, an appropriate distance can be maintained during installation. For example, in the case of two or more vehicles, at least some of the shielding plates can be used to form an aisle, which allows access to the work area while simultaneously blocking views from the outside.

[0073] The invention further relates to the use of a vehicle and a shielding plate according to the invention for shielding a work area.

[0074] The shielding plate may have a packaging size of, for example, approximately 170 cm x 155 cm x 70 cm. These values ​​may be appropriately selected to adapt the shielding plate to the respective vehicle to which it is to be transported and to which it is to be fixed. By appropriately modifying the shielding plate, the shielding plate may be fixed to any vehicle, regardless of the vehicle type or vehicle manufacturer. Due to the weight of the shielding plate (e.g., up to 160 kg), an additional damping element may be provided for the vehicle. The vehicle may be a minibus or minivan, since the rear of this vehicle type is well suited to fixing the shielding plate. This type of vehicle is also preferred as an emergency vehicle in many countries due to the higher visibility of this type of vehicle compared to cars, especially when used on highways. The vehicle may also be a fire engine, such as a fire extinguishing vehicle.

[0075] For purposes of this disclosure, designations such as "floor," "rear," etc., relate to the intended operating state of the vehicle.

[0076] The invention will be explained in more detail below with reference to the illustrations of several embodiments, which are particularly preferred exemplary embodiments, but to which the invention should not be limited. [Brief explanation of the drawings]

[0078] FIG. 1a shows a shielding plate 1a installed along a linear path. The shielding plate 1a has eight frames 2 connected to each other via joints 3. One of the two outer frames 2 is connected to two fixing elements 5 via spacers 4, each of which has a recess (not shown) for connecting to a suitable location on the vehicle's exterior, such as a hook. The frames 2 are connected to the spacers 4 via joints 6. The spacers 4 have two diagonal struts 7 for increased rigidity. The frame 2 connected to the spacer 4 is connected to a metal shielding plate element 8, and each of the remaining frames 2 is connected to a net vinyl shielding plate element 8 with three slats 8a that can move relative to each other. The slats 8a are connected to each frame 2 via elastomer bands 9 (shown in FIG. 2c). Two opposing folding support legs 10 are fixed to every two frames 2 so that the installed shielding plate 1a is supported in a V-shape (or more precisely, an inverted V-shape). Furthermore, a support wheel 11 is fixed to the frame 2 via a telescopic rod 12 for every two frames 2. The support legs 10 and the support wheels 11 are arranged alternately on the frame 2. The linear arrangement of the frames 2 in Fig. 1a makes it possible to additionally connect every two frames 2 by a drop bar latch 13 fixed to every two frames 2, so that the frames arranged in the area between two support legs 10 are firmly connected to each other.

[0079] Figure 1b shows a further shielding plate 1b in the installed state. The shielding plate 1b is constructed similarly to the shielding plate 1a shown in Figure 1a, but has nine frames 2 arranged to pivot relative to one another. The number of joints 3 between the frames 2 also differs from that of the shielding plate 1a shown in Figure 1a.

[0080] Figure 1c shows a portion of a shielding plate 1c, which is constructed substantially similarly to the shielding plate 1a shown in Figure 1a, but differs from the one described above in that the locking element 5 has a three-finger gripper.

[0081] FIG. 2a shows a portion of a shielding plate. It shows a frame 2 connected to a shielding plate element 8 having three slats 8a. Each of the slats 8a is connected to the frame via two separate elastomeric bands 9. Thus, in each case, three elastomeric bands 9 are stretched parallel to two opposing sides of the frame 2, adjacent to these sides (see FIG. 2c). In this case, in each case, two elastomeric bands 9 stretched on opposing sides of the frame 2 form an elastomeric band pair. Each slat 8a is held by a pair of elastomeric bands so that the slats 8a are offset from one another within the frame 2 and are therefore movable relative to one another. In FIG. 2a, the slats 8a are arranged one above the other, which can facilitate installation of the shielding plate by reducing the wind attack surface (like the surface of a sail) and the associated wind loads, and can also facilitate the easy temporary opening of an already installed shielding plate, for example, for a person to pass through. On two sides of the frame 2, portions of couplings 3 for connection to other frames 2 are fixed. Furthermore, the illustrated portion of the shielding plate shows support wheels 11 fixed to the frame by telescopic rods 12. On one side of the frame 2 adjacent to the two sides on which portions of the couplings 3 are fixed, recesses 14 are provided for receiving corresponding protrusions of drop bar latches 13 fixed to the adjacent frame 2.

[0082] Figures 2b-2c show a further part or section of a shielding plate. A frame 2 is shown connected to a shielding plate element 8 having three slats 8a. Each of the slats 8a is connected to the frame via two separate elastomeric bands 9. Thus, in each case, three elastomeric bands 9 are stretched parallel to two opposing sides of the frame 2, adjacent to these sides. In each case, two elastomeric bands 9 stretched on opposing sides of the frame 2 form an elastomeric band pair. Each slat 8a is held by a pair of elastomeric bands on its two narrow sides so that the slats 8a are offset from one another within the frame 2 and can therefore move relative to one another. The adjacent arrangement of the slats 8a according to Figures 2b-2c allows for good shielding of the work area. Parts of the fittings 3 for connecting to other frames 2 are fixed to two sides of the frame 2. One side of the frame 2 adjacent to these two sides is provided with a recess 14 for receiving a corresponding protrusion of a drop bar latch 13 (shown for example in Figure 1c) fixed to the adjacent frame 2. The part of the screen shown in Figure 2b also shows a support wheel 11 fixed to the frame 2 via a rod 12. A support leg 10 is also provided which leans against the frame 2 and is articulatedly connected to it via a clamp 15.

[0083] Figure 3a shows the shielding plate of Figure 2b with the support legs 10 unfolded, thereby supporting the frame 2 in a V-shape (more precisely, an inverted V-shape). Struts 16 are provided between the frame 2 and each of the support legs 10. The support legs 10 have flat, foldable support surfaces 17 that are unfolded in the installed state of the shielding plate to ensure good stability on hard surfaces (e.g., asphalt). The support legs 10 are movable relative to the frame 2 and, due to their geometric shape (see Figures 3b-3c), can be held in a specific position by screws 18 provided in the frame 2.

[0084] 3b-3c show detailed views of a portion of the shielding plate shown in FIG. 2c in the transport position. Two opposing support legs 10 rest against the frame 2. The support legs 10 have sharp recesses 19 at both ends, and this geometric shape allows them to be held in place by screws 18 fixed to the frame 2. FIG. 3b shows the upper region of the frame 2, where the support legs 10 are visible connected to the frame 2 via clamps 15. The clamps 15 have two hinge joints (not shown) to which the support legs 10 are connected so that they can be unfolded when the shielding plate is installed. FIG. 3c shows the lower region of the frame 2, where it can be seen that each of the support legs 10 has a flat support surface 17. Each of the support surfaces 17 can be rotated relative to the respective support leg 10 via hinge joints 20 and folded up for transporting the shielding plate.

[0085] 4a-4b show various perspective views of a portion of a shielding plate in the transport position, with frames 2 connected to each other via joints 3 folded. Each frame 2 is connected to a shielding plate element 8. Each shielding plate element 8 has three slats 8a connected to the frame 2 via elastomeric bands 9. In FIGS. 4a-4b, the slats 8a of all frames 2 are arranged one above the other. Each frame 2 is provided with a support wheel 11 fixed to one side of the frame 2 via an extendable rod 12. The frame also has a recess 14 for receiving a drop bar latch 13 (shown for example in FIG. 1c) of an adjacent frame.

[0086] 5a-5b show a vehicle 21 or a part thereof, on whose rear side 22 (shown in FIGS. 6a-6c) a shielding plate 1d is fixed in a transport position. Guide rails 24 are fixed in the area of ​​the floor and roof 23 of the vehicle 21. These guide rails are arranged close to the two longitudinal sides 25 and the rear side 22 of the vehicle 21 and are curved in the corner areas 26, with a curvature radius of 40 cm. Each guide rail 24 is correspondingly U-shaped. For increased rigidity, the guide rails 24 have struts 27 fixed to the roof 23 and / or floor of the vehicle 21 and arranged perpendicular to the guide rails 24. A portion 28 of the guide rails 24, fixed to the floor of the vehicle 21 near the wheels 29 of the vehicle 21, is removable so as not to interfere with wheel changes. As can be seen in Figures 5a-5b, the shielding plate 1d is connected to two guide rails 24 by two fastening elements 5, each having a three-finger gripper 30 (shown diagrammatically). The connection is made by receiving the guide rails 24 in circular or oval recesses in the three-finger grippers 30 and then screwing them together. The three-finger grippers 30 contain elastomers so that the individual fingers of the three-finger grippers 30 can stretch relative to each other to allow movement of the shielding plate 1d along the curved corner regions 26 of the guide rails 24. The frame 2, connected via joints 3, is folded to transport the shielding plate 1d. The spacer 4 is positioned to pivot 90° relative to the frame 2 to which it is connected via joints 6 so that the shielding plate 1d rests directly against the rear side 22 of the vehicle 21. Each second frame 2 has a drop bar latch 13 for connecting to the adjacent frame 2. The frame 2 also has a recess 14 for receiving the drop bar latch 13. Figure 5b also shows two tensioning elements 31 in the form of tensioning clamps fixed to the frame 2 to prevent the frame 2 from accidentally pivoting relative to each other in the transport position.

[0087] 6a-6c show the vehicle 21 already shown in FIGS. 5a-5b with the shielding plate 1d or a portion thereof during the installation process in the work area. The shielding plate 1d is connected to guide rails 24 of the vehicle 21, which are fixed to the floor and roof 23 by respective fixing elements 5 with three-finger grippers 30 (shown diagrammatically). In contrast to the transport position (see FIG. 5), the spacer 4 and the frame 2 connected thereto via joints 6 are pivoted relative to each other. To install the shielding plate 1d, the folded frame 2 connected to each other via joints 3 can be at least partially unfolded. As a result, the shielding plate 1d can be in one of the positions shown in FIGS. 1a-1b. Due to the U-shape of the guide rails 24, the shielding plate 1d can be installed starting from one of the two longitudinal sides 25 or from the rear side 22 of the vehicle 21, which allows for great flexibility. Thus, in Figure 6a, the shielding plate 1d is positioned near the exterior mirror on the longitudinal side 25 of the vehicle 21, in Figure 6b, it is positioned near the wheel 29 on the longitudinal side 25 of the vehicle 21, and in Figure 6c, it is positioned within the curved corner region 26 of the guide rail 24.

[0088] FIG. 7 shows a further shield plate 1e in the transport position. The shield plate 1e has two fixing elements 5 for fixing to the vehicle. The fixing elements 5 are designed as three-finger grippers 30, the two outer fingers 32 of which are designed to be extensible (see the detailed view in FIG. 8b). Each of the three fingers 32 is rotatably fixed to a separate carriage 33. As a result, the shield plate 1e can be moved along the curved corner area 26 of the guide rail 24 of the vehicle (see FIGS. 8a to 8d). The shield plate 1e shown in FIG. 7 has slats 8a that can be moved relative to each other by means of guide rails (not shown) provided on the frame 2.

[0089] 8a-8d show a vehicle 21, or a part thereof, on which the shielding plate 1e already shown in FIG. 7 is fixed in a transport position on the rear side 22 (shown in FIGS. 6a-6c). As shown in the detailed view of FIG. 8b, the outer two fingers 32 of the three-finger gripper 30 have an inner portion 34 that is extendable from an outer portion 35 in order to change the length of the two outer fingers 32. Each of the three fingers 32 is fixed to a separate carriage 33 using a swivel joint (not shown). The three-finger gripper 30 is also fixed to a fixing element 5 by a swivel joint (not shown). The carriage 33 is fixed to guide rails 24 arranged in the floor and roof 23 area of ​​the vehicle 21 by a screw connection (not shown). In FIG. 8d, the vehicle 21 is shown only by the guide rails 24 and wheels 29 to illustrate the fixing of the shielding plate 1e to both guide rails 24.

[0090] Figure 9a shows a portion of a shield 1f with a weather shield 36 fixed to the frame 2. The shield 1f is in an installed state. The weather shield 36 is arranged at an angle of approximately 90° to the frame 2 and can protect people in the work area from rain. Figure 9b shows a portion of the vehicle 21 with the shield 1f fixed in a transport position. The weather shield 36 can protect the shield 1f from rain in said transport position.
